Study shows aging affects adaptive immune responses

Today at the 45th Annual Meeting & Exhibition of the American Association for Dental Research, researcher Jeffrey Ebersole, University of Kentucky, Lexington, USA, will present a study titled "Systemic Antibody Responses to Oral Bacteria with Aging." The AADR Annual Meeting is being held in conjunction with the 40th Annual Meeting of the Canadian Association for Dental Research.

Aging-associated changes begin earlier than expected in human brain

A new study published in Physiological Genomics suggests that the brain shows signs of aging earlier than old age. The study found that the microglia cells—the immune cells of the brain—in middle-aged mice already showed altered activity seen in microglia from older mice.

Researchers reveal link between necrotizing enterocolitis and uropathogenic E. coli

Necrotizing enterocolitis is an intestinal disease that afflicts about one in 10 extremely premature infants and is fatal in nearly one-third of cases. The premature infant gut is believed to react to colonizing bacteria, causing damage to the intestinal walls and severe infection.

UCMR researchers discover compounds that can attenuate virulence of Listeria monocytogenes

Scientists at Umea Centre for Microbial Research have discovered chemical compounds which are able to attenuate the virulence of the bacterial human pathogen Listeria monocytogenes. Their findings are published today in the high impact journal Cell Chemical Biology.

UC San Diego researchers use CRISPR-Cas9 system to target RNA in living cells for first time ever

The genetic code stored in DNA determines everything from the color of our eyes to our susceptibility to disease. This has motivated scientists to sequence the human genome and develop ways to alter the genetic code, but many diseases are linked to a different fundamental molecule: RNA.

Older types of arthritis medicine appear to be dangerous for the heart

Many Danes are prescribed NSAIDs for the treatment of painful conditions, fever and inflammation. But the treatment also comes with side effects, including the risk of ulcers and increased blood pressure.

Automated techniques could dramatically accelerate antimicrobial discovery

The antimicrobial arsenal that we count on to save millions of lives each year is alarmingly thin--and these microbes are rapidly evolving resistance to our weapons. But help may be on the way: In a study posted in the AMB Express, researchers from the National Institute of Standards and Technology show that automated techniques commonly used to screen new drugs for mammalian cell toxicity could also dramatically speed up the challenging task of antimicrobial discovery.

Researchers report fast, accurate technique for monitoring bacterial growth in packaged food

It's important to know how microorganisms -- particularly pathogenic microbes -- grow under various conditions. Certain bacteria can cause food poisoning when eaten and bacterial growth in medical blood supplies, while rare, might necessitate discarding the blood.

Study: Statin drugs can reduce time to clear tuberculosis infection in mice

In a study using mice, the Johns Hopkins University School of Medicine infectious disease experts have added to evidence that statin drugs — known primarily for their cholesterol-lowering effects — can significantly reduce the time it takes to clear tuberculosis infection.

Research shows probiotic B. longum KACC 91563 has ability to reduce effects of food allergies

Lactobacillus might sound familiar when the topic of probiotics comes up, but they are only one of many types of bacteria that have proven health benefits.

Could prebiotics benefit early life brain development? An interview with Dr Phil Burnet

Galacto-oligosaccharides are essentially sugar or saccharide molecules that have been joined together into short polymer chains.

Global research links genes to five common, hard-to-treat inflammatory diseases

A global study involving 50 different research centres has found hundreds of genes which cause five common, hard-to-treat and debilitating inflammatory diseases, paving the way to new treatments for these conditions

Researchers describe antibiotic resistance as either selfish or co-operative

Trace concentrations of antibiotic, such as those found in sewage outfalls, are enough to enable bacteria to keep antibiotic resistance, new research from the University of York has found. The concentrations are much lower than previously anticipated, and help to explain why antibiotic resistance is so persistent in the environment.

MU researchers discover microbiome that may be linked to male reproductive disorders

Research shows that bacteria can be beneficial to body processes such as digestion; however, some bacteria housed in the human body may cause disease. These specialized communities of bacteria in the body are known as microbiomes.

Researchers discover potentially-pathogenic bacteria in water supply pipes

The human microbiome, a diverse collection of microorganisms living inside us and on our skin, has attracted considerable attention for its role in a broad range of human health issues. Now, researchers are discovering that the built environment also has a microbiome, which includes a community of potentially-pathogenic bacteria living inside water supply pipes.

One-fourth of seniors acquire new superbugs during hospital stay

One in four seniors is bringing along stowaways from the hospital to their next stop: superbugs on their hands.Moreover, seniors who go to a nursing home or other post-acute care facility will continue to acquire new superbugs during their stay, according to findings made by University of Michigan researchers published today in a JAMA Internal Medicine research letter.

Russian scientists propose new technique to analyze intestinal metagenomes

A group of Russian scientists, among them staff at the Moscow Institute of Physics and Technology, have proposed a new method for the comparison of metagenome-coupled DNA sequences from all of the organisms in a sample of biological material being investigated.

PKM2 enzyme plays major role in early steps of wound healing

An enzyme involved in glucose metabolism in cells plays a major role in the early steps of wound healing, a finding that could lead to new therapeutic approaches for wound care, according to researchers at Georgia State University.

Discovery of new strain of bacteria could aid in developing effective oral probiotic

University of Florida Health researchers have identified a new strain of bacteria in the mouth that may keep bad bacteria in check -- and could lead to a way to prevent cavities using probiotics.The researchers say the findings could lead to the development of a supplement that patients could take orally to prevent cavities

Conserved gene can act to inhibit lung cancer development, study finds

Scientists believe that "conserved" genes — those found in life forms that range from bacteria to plants, insects and humans — perform vital biological functions across species. And limited research on one of those genes, Nitrilase 1 (Nit1), suggested it acts to inhibit cancer development.
